Fraud prevention built for issuers, at scale

Reduce Fraud Losses. Protect Your Customers. Strengthen Your 3DS Defense.
Built on your own data

Every score and detection draws on data only the issuer holds: transaction history, registration changes, cardholder records and more, for a fuller picture than scheme-level scoring alone.

Stops what scheme scores miss

Card testing, account takeover and social engineering often pass standard checks unnoticed. Dedicated detection catches each pattern in real time, before it reaches your cardholders

No rip-and-replace


Every capability plugs into the existing ACS and fraud environment, so issuers add protection without replacing tools or disrupting current workflows.

Built for developers, backed by compliance

How the platform plugs into your setup, decides in real time, and stays compliant
Architecture and Integration

Cloud-native, API-first: 3DScore, BIN Attack Score, registration data and cardholder master data integrate via RESTful APIs directly into your existing ACS and fraud environment; no rip-and-replace, integrate in days not months. 

Detection and prevention run in real time, 24/7. Every rule can be simulated on historical data in RiskShield before going live. A dedicated onboarding team gets you live fast, with minimal effort on your side. 
 

From score to decision

A 3DS transaction enters the ACS, 3DScore is computed from data only the issuer holds, and the score is used on its own or combined with existing knowledge-based rules in RiskShield.

A decision, approve, step-up, decline or alert, is returned in milliseconds. Example rule: trigger step-up authentication above one score, decline and alert above a higher one.

Security and compliance

Stay compliant, stay ahead. Full support for the latest EMV 3DS protocol, automated scheme updates, and PSD2 and SCA readiness, backed by a complete audit trail and reporting. 

Certified to EMVCo, ISAE 3402, ISO 27001, PCI 3DS, and PCI DSS standards. Continuous, automated monitoring and alerting keep your issuing business audit-ready and secure, without adding operational burden on your teams

Compliant with 3-D Secure schemes’ programs

FAQs

Straight answers to the questions issuers ask most often before switching their Access Control Server. 
What makes G+D Netcetera's fraud prevention different?

3DScore, the BIN Attack Score, real-time registration data integration and cardholder master data integration work together as one service, or stand alone if you only need one. Every capability plugs into your existing ACS without a rip-and-replace, runs 24/7 in real time, and the BIN Attack Score has won a Platinum Award for Fraud Prevention at the Juniper Research Future Digital Awards 2025. More than 1,200 banks worldwide already run the service. 

How does 3DScore compare to our scheme's score?

At the false-positive range issuers actually operate in, 3DScore detects up to 33% more fraud than standard scheme scoring. Performance is tracked daily inside RiskShield, so you see how it's actually performing. 

Do we need to replace our existing fraud tools?

No. 3DScore, the BIN Attack Score, real-time registration data integration and cardholder master data integration all plug directly into your existing ACS and fraud environment as separate capabilities, so you can adopt one or all four. The service runs real-time, automated detection 24/7 with no manual monitoring required, and is compliant by design with PSD2 and PCI DSS without compromising the cardholder experience.
